Wash the mini-split filters

Lift the indoor unit's front panel, slide the mesh filters out, wash and dry them, and refit them. Coil and blower cleaning stay a pro's.

8 steps

Tap a step to watch it again.

Turn the unit off with its remote and wait for its louver to close.
Use a step stool, not a chair, to reach it.
Hold the panel by its sides and lift it until it stays open.
Pull each mesh filter down and out of its slots.
Vacuum the dust off, then rinse them under lukewarm water from the back. A little dish soap for grease.
Shake them off and let them dry in the shade, not in the sun or with heat.
Slide each filter back into its slots, and close the panel until it clicks.
Run it with the remote. The air should flow freely.
Black spots on the coil or blower, a musty smell, or water dripping from the unit: ask Handyman for a heating and cooling tech.
